This series fixes a few issues found while writing a clk driver for a new SoC (Bouffalo Lab BL808), and adds the new functionality needed to implement a hierarchy of clocks in a single device (without the CCF). The .get_parent hook will be useful on other platforms as well; I plan to use it to implement PLL rate setting on sunxi.
Samuel Holland (6): clk: Handle error pointers in clk_valid() clk: Fix error handling in clk_get_rate() clk: Fix error handling in clk_get_parent() clk: Fix rate caching in clk_get_parent_rate() clk: Remove an unneeded check from clk_get_parent_rate() clk: Add a .get_parent operation
